STOVEPIPE CLAMP.

Application filed May 23,

To all whom it may concern.

Be it known that 1, MICHAEL J. DEARDA, a citizen of the United States, residing at St. Louis, State of Missouri, have invented certain new and useful Improvements in Stovepipe Clamps, of which the following is a specification.

This invention relates to certain new and useful improvements in stove pipe clamps, the peculiarities of which will be hereinafter fully described and claimed.

lhe main object of my invention is to provide a brace that will force outward diametrically the sides of a stove pipe at the end that is inserted in a chimney .hole, thereby frictionally engaging the outer diameter of the pipe with the side of the chimney hole; and secondly, to provide a special form of such a brace.

In the accompanying drawing on which like reference numerals indicate correspondii'ig parts, Fig. 1 represents a face View of a chimney having a hole adapted for reception of a stove pipe located therein and my clamp applied thereto; Fig. 2, a horizontal secv tional plan view through 22 of Fig. 1;

Fig. 8, a detail view of one member of my clamp; Fig. l, a similar view of the other member; Fig. 5, an edge view of my clamp as folced for packing in multiple; Fig. 6, an end view of Fig. 5; and Fig. 7 an underside view of my clamp with the members adjusted for a larger diameter of pipe than shown in Figs. 1 and 2 and indicated in engagement therewith as shown by broken lines.

3 designates a chimney wall and d the usual thimble cemented in the chimney hole for the reception of a stove pipe 5 leading to the line in said chimney. llhere is always slight play or clearance between the end of the stove pipe and thimble or sides of the chimney hole. and in order to hold the pine firmly in said hole 1 provide a brace,

' rably in the form of two members 6 *5 having ends 8 serrated or otherwise an; adapted to engage the inside of the stove pipe as shown in Figs. 1 and 2, and the inner ends of said members are pivotally connected by means of a cross bar 9 on one member insertable into holes 10 on side lugs 11 of the other member. The outer ends of the memhere may thus be brought closer together and the clamp may be readily inserted in the stove pipe in a bent position and then the bracing action may be given to the pipe by 1923.

straightening the members to the position shown in Fig. l. The outside of the pipe is thus engaged frictionally with the sides of the thimble, or the chimney hole, at diametrical points as shown in Fig. 1, and prevents accidental dislodgment of the pipe from the hole.

Other form of engagement of the inner ends of the members may be employed, but I prefer to form the members from flat plate pieces stamped out by dies or otherwise as shown in Figs. 3 or 1.. and then bent up along the dotted lines of 3 to form the side lugs 11, and the end 9 doubled on the dotted line of 4;, or otherwise formed to constitute a pivotal bar for insertion in the holes 10. These holes 10 are in multiple and in pairs at different distances from the outer end of the member, so that the pivotal bar 9 of the other member may be inserted in a pair of holes further from the serrated end, and form a jointed brace of longer bracing length suitable for a larger size of pipe than that shown in Figs. 1 and 2; such varied length of brace is shown in Fig. 7.

By my form of jointed brace the two menbers can be folded together as shown in Fig. 5, to facilitate packing. The plate form and my construction makes a simple, effective and cheap cross brace adapted for the purpose described.

I claim:

1. A stove pipe clamp comprising two members pivoted together forming a jointed brace,-the outer ends of said members being serrated for frictional engagement with the inside of a stove pipe and the inner ends having a variable pivotal engagement with each other, thereby adapting the clamp to pipes of more than one diameter.

2. A stove pipe clamp comprising two members detachably pivoted together constituting a ointed brace and formed by fiat thin plates,-one plate member having per forated side lugs at the inner end and the other member having a pivot bar its inner end adjustably mounted in the perforated side lugs, and the outer ends of said members being adapted for outward pressure and frictional engagement with the inside of a stove pipe when the brace is extended to normal position.

In testimony whereof I have affixed my signature.
